Using the 2011 Mw9.0 Tohoku earthquake to test the Coulomb stress triggering hypothesis and to calculate faults brought closer to failure
Shinji Toda, Jian Lin, Ross S. Stein
2011, Earth, Planets and Space (63) 725-730
The 11 March 2011 Tohoku Earthquake provides an unprecedented test of the extent to which Coulomb stress transfer governs the triggering of aftershocks. During 11-31 March, there were 177 aftershocks with focal mechanisms, and so the Coulomb stress change imparted by the rupture can be resolved on the aftershock nodal...

Kurt J. Jenkins, Paul C. Griffin, John R. Boetsch, Carla Cole
2011, Natural Resource Report NPS/NCCN/NRR—2011/455
Maintaining elk (Cervus elaphus roosevelti) herds that frequent Lewis and Clark National Historical Park (NHP) is central to the park’s purpose of preserving the historic, cultural, scenic, and natural resources. Elk were critical to sustaining the members of the Lewis and Clark expedition by providing food and clothing over the...

W. Mark Ford, Eric R. Britzke, Christopher A. Dobony, Jane L. Rodrigue, Joshua B. Johnson
2011, Journal of Fish and Wildlife Management (2) 125-134
White-nose Syndrome (WNS), a wildlife health concern that has decimated cave-hibernating bat populations in eastern North America since 2006, began affecting source-caves for summer bat populations at Fort Drum, a U.S. Army installation in New York in the winter of 2007–2008. As regional die-offs of bats became evident, and Fort...
Seasonal productivity in a population of migratory songbirds: why nest data are not enough
Henry M. Streby, David E. Andersen
2011, Ecosphere (2) 1-15
Population models for many animals are limited by a lack of information regarding juvenile survival. In particular, studies of songbird reproductive output typically terminate with the success or failure of nests, despite the fact that adults spend the rest of the reproductive season rearing dependent fledglings. Unless fledgling survival does...
Occurrence and distribution of Asian carps in Louisiana
R. Glenn Thomas, Jill A. Jenkins, Jody David
2011, Book chapter, Invasive Asian Carps in North America
In the 1970s, commercial fishers reported sightings of grass carp Ctenopharyngodon idella in large rivers and associated backwaters of Louisiana; the first specimen in Louisiana Department of Wildlife and Fisheries' fishery independent sampling was recorded in 1976. Beginning in the early 1980s, commercial fishers noted increasing populations of bighead carp...
Guidance manual for forensic analysis of perchlorate in groundwater using chlorine and oxygen isotopic analyses

Guleid A. Artan, S.A. Tokar, D.K. Gautam, S.R. Bajracharya, M.S. Shrestha
2011, Journal of Flood Risk Management (4) 360-373
In Nepal, as the spatial distribution of rain gauges is not sufficient to provide detailed perspective on the highly varied spatial nature of rainfall, satellite-based rainfall estimates provides the opportunity for timely estimation. This paper presents the flood prediction of Narayani Basin at the Devghat hydrometric station (32 000 km2) using bias-adjusted...

Ashwin Naidu, Robert R. Fitak, Adrian Munguia-Vega, Melanie Culver
2011, Molecular Ecology Resources (12) 191-196
Sequence-based species identification relies on the extent and integrity of sequence data available in online databases such as GenBank. When identifying species from a sample of unknown origin, partial DNA sequences obtained from the sample are aligned against existing sequences in databases. When the sequence from the matching species is...

Development of a pan-Arctic monitoring plan for polar bears: Background paper
Dag Vongraven, Elizabeth L. Peacock
2011, Report
Polar bears (Ursus maritimus), by their very nature, and the extreme, remote environment in which they live, are inherently difficult to study and monitor. Monitoring polar bear populations is both arduous and costly and, to be effective, must be a long-term commitment. There are few jurisdictional governments and management...

Jonathan S. Caine, Anna B. Wilson
Robert Blair, George Bracksieck, editor(s)
2011, Book chapter, The Eastern San Juan Mountains Their Ecology, Geology, and Human History
Knowledge of the occurrence, storage, and flow of groundwater in mountainous regions is limited by the lack of integrated data from wells, streams, springs, and climate. In his comprehensive treatment of the hydrogeology of the San Luis Valley, Huntley (1979) hypothesized that the underlying, fractured volcanic bedrock of the San...
